Sticky VGT.

Well, hell. Maybe it's time I changed my direction. I'm going to want it done in person by someone I trust and that will stand behind making it completely right though. That's the scary part. I sure wish I lived closer to Plain City Ohio.

Come on up!
 
and shoot groundhogs. tuning to me is always gonna be shady..i know it aint..and it tune my sxs...and my harley....and gonna do the anteater cuz i cant sell it so im gonna install it and fuk up my truck...im int in this tune also jory.....mines not bad tho....you towed with it..wasnt good for ya? might be the head and cam and the dj engine but mine is a beast with a load and the brake with the camper is semi like..it downshifts all the way into first in tow haul
 
I wish I had an actual use for a diesel sometimes. Mine has never towed anything mom’s 4runner wouldn’t tow haha.
 
If someone told me my old turbo was the Cheetah and the new one was the stock one, I'd believe it. I can tell absolutely zero difference between the stock turbo and the Cheetah except for the stock e-brake worked much better. I'm still disappointed in the $3000 I spent on it. Maybe with a different tune it will wake it up and let it join the party and impress me.

I’ve often wondered if the Fleece products were worth the astronomical price.

I'm not blaming Fleece. I'm sure with tuning it will be night and day. I guess I just expected a drop-in replacement to be noticeably different. With my truck setup and H&S tuning...it was not. Don't take it as brand bashing. :cool:

This is meant as a legit question, what were you expecting to be different? I've been going back and forth on this for a while and in my head, I guess I assumed I'd need new tuning to take advantage of the 'potential' of the new turbo.

This is pure ignorance as I don't know squat about tuning and such, but it would seem if nothing changes, dropping in a replacement would yield the same results as previous since everything else is staying the same. At best I could see it just doing things more efficiently; ie. better EGT's. I don't know electronically how it works, but wouldn't you need to 'turn it up' to see a difference?

You can't tell a difference anywhere in the powerband? The stock turbo falls pretty hard after 2500 rpm, the additional 3mm should be noticeable at higher rpms.

A Cheetah can technically not create more back pressure/braking then the stock turbo, as 100% closed vane position is 100%. Tuning however can command 100% earlier.

The exhaust brake issue makes me wonder if you have a ebp sensor issue or if the cheetah vgt actuator needs to be calibrated. A bunch of guys over on CF had issues and needed to recalibrate after install, but most of those threads were on 13+ trucks.

I don't just flog this old girl much so I'm not sure if the power band is there or not. What I can tell you is that it doesn't whoa near as good as the factory when we took it out. EBP sensor was fine before the install so I'm not thinking it crapped out during the swap. I don't think it's ever getting to 100%. Maybe I need to take the truck back to the shop and have Trent see what command and actual readings are and compare the two. Something has to be missing here. This turbo uses the same actuator as the 13+ trucks so maybe it's a calibration issue. I'll have to dust the username off on CF and go see what all those asshats have to say. :D

I wonder if we're reaching the point of diminishing returns we did on bikes, ATV's, and PWC's years ago, where the stock engines were tweaked and putting out so much power that bolt-on mods were no longer of any benefit, especially for the cost.

Back in the day, you could put a pipe, a set of carbs, and a head on a 550 JetSki and almost double the power. Same on a dirt bike or ATV. Back in the day, you could put a turbo, some injectors, and change the timing on a 12-valve and quadruple the power. Can't do any of that today.

I see your point and agree. However, when replacing a stock item with an aftermarket item of greater cost and quality (assumed) then it's kinda disappointing to go backwards in performance. I talked to Trent. We are going to put a reader on it next time I head north and see if commanded is 100% and actual is 100%. Right now, I'm going with it need calibrated until proven guilty in a courth of law.
 
i didnt calibrate mine...have ya chatted with fleece? mines an 08 so idk...but my brake is great. better than the stock one was..esp in tow haul itll brake down to 15 mph if the trlr is pushing it dwonhill

Yes, I chatted with Fleece in email form. They question the sensor as well but I fail to see how that failed during the install.

You never know. I put a new tune on my dirt bike a while back and it ran like crap at WOT. Asked the tuner about it and he told me to change the spark plug. I figured he was passing the buck but put a new plug in anyways and it ran great.

Anyways don't complain, at least you're not driving a Ford which has pretty much no exhaust brake at all compared to the Rams.
 
My flat screen display was reading 58 psi drive pressure the entire day Saturday while I hauled hay. Maybe the stupid EBP sensor IS stuck. I'll have to look into that now. What are the chances the stupid sensor craps the exact same time the vanes or actuator fails? My luck.
